Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...

In this paper we present a Video Processing Platform (VPP) for rapid prototyping based on FPGA (Field Programmable Gate Arrays) architecture using EDK embedded system and Xilinx System Generator. This hardware/software co-design platform has been implemented on a Xilinx Spartan 3A DSP FPGA. The video interface blocks are done in RTL and the MicroBlaze soft processor is used as an embedded video...

We present the architecture of a system, based on a PC, covering real-time video processing by integration of live video and computer graphics. The video processing and integration are realized by generation and evaluation of an on-line MIPmap video texture. This new application of a known filtering technique for still textures in the field of live video processing permits an easy and high perf...

compressed domain processing, transcoding, video editing, MPEG, splicing, reverse play, frame rate conversion, interlace to progressive, motion vector resampling Video compression algorithms are being used to compress digital video for a wide variety of applications, including video delivery over the Internet, advanced television broadcasting, video streaming, video conferencing, and video stor...

This paper presents a set of components for video processing and browsing. The current framework comprises a toolkit, with objects for video segmentation, processing and support for interactive applications. An approach to video modeling for knowledge based parsing of multimedia information is outlined. Some applications of the toolkit and auxiliary tools are described with emphasis on WWW rela...

The concept of an image being created by superposition of object layers has been used by photograph editors for many many years. Adobe Photoshop has been using this idea since 1989. In 1994, Wang and Adelson presented an article in which they gave serious credence to the idea that each frame in an image sequence can be constructed by layers of object planes. This is a much more realistic idea. ...

This paper represents a method to stabilize the frame rate of real-time free-viewpoint video generation. When we apply real-time free-viewpoint video to live video broadcasting, the frame rate of video processing should be constant. Otherwise, presented video gives viewers unnatural feeling due to time inconsistency. Our method to generate freeviewpoint video is based on 3-D shape reconstructio...
